The broadcast channel may include asatellite channel and a terrestrial channel. At least two broadcastreceiving modules 111 can be provided to the mobile terminal 100 inpursuit of simultaneous receptions of at least two broadcast channels orbroadcast channel switching facilitation.

The broadcast managing server generally refers to a server whichgenerates and transmits a broadcast signal and/or broadcast associatedinformation or a server which is provided with a previously generatedbroadcast signal and/or broadcast associated information and thentransmits the provided signal or information to a terminal. Thebroadcast signal may be implemented as a TV broadcast signal, a radiobroadcast signal, and a data broadcast signal, among others. If desired,the broadcast signal may further include a broadcast signal combinedwith a TV or radio broadcast signal.

The broadcast associated information includes information associatedwith a broadcast channel, a broadcast program, a broadcast serviceprovider, etc. And, the broadcast associated information can be providedvia a mobile communication network. In this case, the broadcastassociated information can be received by the mobile communicationmodule 112.

The broadcast associated information can be implemented in variousforms. For instance, broadcast associated information may include anelectronic program guide (EPG) of digital multimedia broadcasting (DMB)and electronic service guide (ESG) of digital video broadcast-handheld(DVB-H).

The broadcast receiving module 111 may be configured to receivebroadcast signals transmitted from various types of broadcast systems.By nonlimiting example, such broadcasting systems include digitalmultimedia broadcasting-terrestrial (DMB-T), digital multimediabroadcasting-satellite (DMB-S), digital video broadcast-handheld(DVB-H), Convergence of Broadcasting and Mobile Service (DVB-CBMS), OpenMobile Alliance-BroadCAST (OMA-BCAST), China Multimedia MobileBroadcasting (CMMB), Mobile Broadcasting Business Management System(MBBMS), the data broadcasting system known as media forward link only(MediaFLO®) and integrated services digital broadcast-terrestrial(ISDB-T). Optionally, the broadcast receiving module 111 can beconfigured suitable for other broadcasting systems as well as theabove-explained digital broadcasting systems.

The broadcast signal and/or broadcast associated information received bythe broadcast receiving module 111 may be stored in a suitable device,such as a memory 160.

Currently, location and time informations are calculatedusing three satellites, and errors of the calculated location positionand time informations are then amended using another satellite. Besides,the GPS module 115 is able to calculate speed information bycontinuously calculating a real-time current location.

Referring to FIG. 1, the audio/video (A/V) input unit 120 is configuredto provide audio or video signal input to the mobile terminal 100. Asshown, the A/V input unit 120 includes a camera 121 and a microphone122. The camera 121 receives and processes image frames of stillpictures or video, which are obtained by an image sensor in a video callmode or a photographing mode. And, the processed image frames can bedisplayed on the display 151.

The image frames processed by the camera 121 can be stored in the memory160 or can be externally transmitted via the wireless communication unit110. Optionally, at least two cameras 121 can be provided to the mobileterminal 100 according to environment of usage.

The microphone 122 receives an external audio signal while the portabledevice is in a particular mode, such as phone call mode, recording modeand voice recognition.

The display 151 is typically implemented to visually display (output)information associated with the mobile terminal 100. For instance, ifthe mobile terminal is operating in a phone call mode, the display willgenerally provide a user interface (UI) or graphical user interface(GUI) which includes information associated with placing, conducting,and terminating a phone call. As another example, if the mobile terminal100 is in a video call mode or a photographing mode, the display 151 mayadditionally or alternatively display images which are associated withthese modes, the UI or the GUI.

The display module 151 may be implemented using known displaytechnologies including, for example, a liquid crystal display (LCD), athin film transistor-liquid crystal display (TFT-LCD), an organiclight-emitting diode display (OLED), a flexible display and athree-dimensional display. The mobile terminal 100 may include one ormore of such displays.

Some of the above displays can be implemented in a transparent oroptical transmittive type, which can be named a transparent display. Asa representative example for the transparent display, there is TOLED(transparent OLED) or the like. A rear configuration of the display 151can be implemented in the optical transmittive type as well. In thisconfiguration, a user is able to see an object in rear of a terminalbody via the area occupied by the display 151 of the terminal body.

At least two displays 151 can be provided to the mobile terminal 100 inaccordance with the implemented configuration of the mobile terminal100. For instance, a plurality of displays can be arranged on a singleface of the mobile terminal 100 in a manner of being spaced apart fromeach other or being built in one body. Alternatively, a plurality ofdisplays can be arranged on different faces of the mobile terminal 100.

In case that the display 151 and the touch sensor 137 configures amutual layer structure (hereinafter called ‘touch screen’), it is ableto use the display 151 as an input device as well as an output device.In this case, the touch sensor can be configured as a touch film, atouch sheet, a touchpad or the like.

The touch sensor 137 can be configured to convert a pressure applied toa specific portion of the display 151 or a variation of a capacitancegenerated from a specific portion of the display 151 to an electricinput signal. Moreover, it is able to configure the touch sensor 137 todetect a pressure of a touch as well as a touched position or size.

If a touch input is made to the touch sensor 137, signal(s)corresponding to the touch is transferred to a touch controller. Thetouch controller processes the signal(s) and then transfers theprocessed signal(s) to the controller 180. Therefore, the controller 180is able to know whether a prescribed portion of the display 151 istouched.

Referring to FIG. 2, a proximity sensor (141) can be provided to aninternal area of the mobile terminal 100 enclosed by the touchscreen oraround the touchscreen. The proximity sensor is the sensor that detectsa presence or non-presence of an object approaching a prescribeddetecting surface or an object existing around the proximity sensorusing an electromagnetic field strength or infrared ray withoutmechanical contact. Hence, the proximity sensor has durability longerthan that of a contact type sensor and also has utility wider than thatof the contact type sensor.

The proximity sensor can include one of a transmittive photoelectricsensor, a direct reflective photoelectric sensor, a mirror reflectivephotoelectric sensor, a radio frequency oscillation proximity sensor, anelectrostatic capacity proximity sensor, a magnetic proximity sensor, aninfrared proximity sensor and the like. In case that the touchscreenincludes the electrostatic capacity proximity sensor, it is configuredto detect the proximity of a pointer using a variation of electric fieldaccording to the proximity of the pointer. In this case, the touchscreen(touch sensor) can be classified as the proximity sensor.

For clarity and convenience of the following description, as a pointerbecomes proximate to a touchscreen without coming into contact with thetouchscreen, if the pointer is perceived as situated over thetouchscreen, such an action shall be named ‘proximity touch’. If apointer actually comes into contact with a touchscreen, such an actionshall be named ‘contact touch’. A proximity-touched position over thetouchscreen with the pointer may mean a position at which the pointervertically opposes the touchscreen when the touchscreen isproximity-touched with the pointer.

The proximity sensor detects a proximity touch and a proximity touchpattern (e.g., a proximity touch distance, a proximity touch duration, aproximity touch position, a proximity touch shift state, etc.). And,information corresponding to the detected proximity touch action and thedetected proximity touch pattern can be outputted to the touchscreen.

The audio output module 152 functions in various modes including acall-receiving mode, a call-placing mode, a recording mode, a voicerecognition mode, a broadcast reception mode and the like to outputaudio data which is received from the wireless communication unit 110 oris stored in the memory 160.

The alarm unit 153 is able to output a signal forannouncing the event occurrence by way of vibration as well as video oraudio signal. The video or audio signal can be outputted via the display151 or the audio output unit 152. Hence, the display 151 or the audiooutput module 152 can be regarded as a part of the alarm unit 153.

The haptic module 154 generates various tactile effects that can besensed by a user. Vibration is a representative one of the tactileeffects generated by the haptic module 154. Strength and pattern of thevibration generated by the haptic module 154 are controllable. Forinstance, different vibrations can be outputted in a manner of beingsynthesized together or can be outputted in sequence.

The haptic module 154 is able to generate various tactile effects aswell as the vibration. For instance, the haptic module 154 generates theeffect attributed to the arrangement of pins vertically moving against acontact skin surface, the effect attributed to the injection/suctionpower of air though an injection/suction hole, the effect attributed tothe skim over a skin surface, the effect attributed to the contact withelectrode, the effect attributed to the electrostatic force, the effectattributed to the representation of hold/cold sense using an endothermicor exothermic device and the like.

The haptic module 154 can be implemented to enable a user to sense thetactile effect through a muscle sense of finger, arm or the like as wellas to transfer the tactile effect through a direct contact. Optionally,at least two haptic modules 154 can be provided to the mobile terminal100 in accordance with the corresponding configuration type of themobile terminal 100.

For clarity and convenience of the following description, assume that amobile terminal mentioned in the following description includes at leastone of the components shown in FIG. 1. In particular, assume that amobile terminal 100 according to the present invention includes thewireless communication unit 110, the display unit 151, the memory 160and the controller 180 among the components shown in FIG. 1. The mobileterminal 100 according to the present invention may include the wirelessinternet module 113 and the short range communication module 114configured to perform a short range communication in the wirelesscommunication unit 110 shown in FIG. 1. In particular, the wirelessinternet module 113 may be configured to perform an access to an accesspoint (AP) and the short range communication module 114 may beconfigured to deliver a control signal for controlling an operation ofan external device. The wireless internet module 113 may include a WLANcommunication module configured to perform Wi-Fi communication and theshort range communication module 114 may include an infraredcommunication module configured to perform an infrared communication(IrDA), by which the present invention may be non-limited.

In the mobile terminal 100 according to the present invention, if thedisplay unit 151 includes a touchscreen, it may facilitateimplementation of the present invention. Hence, in the followingdescription, assume that the display unit 151 includes the touchscreen.

Prior to describing operations of the mobile terminal 100 according tothe present invention, a remote controller program for remotelycontrolling an external terminal is described as follows.

First of all, a remote controller program is configured to remotelycontrol operations of an external device. And, the controller 180 isable to generate a control signal for remotely controlling the externaldevice via the remote controller program. Using the remote controllerprogram, the mobile terminal 100 can be used as a traditional remotecontroller. Once the remote controller program is active, the controller180 can control a control board for controlling operations of theexternal device externally to be displayed. This is described in detailwith reference to FIG. 4 as follows.

FIGS. 4A to 4D are diagrams for one example to describe a remotecontroller program according to the present invention.

Referring to FIGS. 4A to 4D, once a remote controller program isactivated, the controller 180 can control a control board 400, which isconfigured to control operations of an external device, to be displayed.In this case, the control board 400 may mean a user interface(hereinafter abbreviated UI) in which buttons for remotely controllingthe operations of the external device are put together. Based on a userinput to the control board 400, the controller 180 generates a controlsignal for remotely controlling an operation of the external device. Thecontroller 180 then transmits the generated control signal to theexternal device, thereby controlling the external device to operatebased on the corresponding control signal.

In FIGS. 4A to 4D, the control board 400 may include tab button regions412, 414, 416 and 418 for selecting external devices to control remotelyand a control button region 420 for controlling operations of theexternal devices. If a user applies a touch input to one of the tabbuttons 412, 414, 416 and 418, the user can specify the external deviceto remotely control. Once the external device to be remotely controlledis specified, the controller 180 can control the specified externaldevice to be identified through an indicator. In FIGS. 4A to 4D, astar-shape indicator 430 is displayed on an activation tab for example,thereby enabling the specified external device to become identifiable.For instance, in FIGS. 4A to 4D, the tab buttons 412, 414, 416 and 418of a TV, a settop box, an audio system and an air conditioner are inactive states, respectively. Hence, through the control boards 400 shownin FIGS. 4A to 4D, operations of the TV, settop box, audio system andair conditioner can be controlled individually and remotely.

The control board 400 shown in FIGS. 4A to 4D shall be sequentiallydescribed as follows.

First of all, referring to FIG. 4A, a power button, a volume adjustbutton, a channel adjust button, a mute button and an external inputbutton are displayed on the TV control board 400 for controlling the TVfor example. The power button shown in FIG. 4A may be understood asprovided to remotely control power ON/OFF of the TV, the volume adjustbutton may be understood as provided to remotely control a volume of theTV, and the channel adjust button may be understood as provided toremotely control a channel of the TV. Moreover, the mute button may beunderstood as provided to set the TV to enter a mute state and theexternal input button may be understood as provided to adjust whether toactivate a TV external input terminal channel.

Referring to FIG. 4B, a power button, a volume adjust button, a channeladjust button, a mute button, an external input button and a numeralbutton are displayed on the settop box control board 400 for controllingthe settop box for example. The power button shown in FIG. 4B may beunderstood as provided to remotely control power ON/OFF of the settopbox, the volume adjust button may be understood as provided to remotelycontrol a volume of the settop box, and the channel adjust button may beunderstood as provided to remotely control a channel of the settop box.Moreover, the mute button may be understood as provided to set thesettop box to enter a mute state and the external input button may beunderstood as provided to adjust whether to activate a settop boxexternal input terminal channel. The numeral button shown in FIG. 4B maybe understood as provided to page a numeral button. If the numeralbutton is paged, a user can adjust a channel of the settop box bymanipulating the numeral button.

Referring to FIG. 4C, a power button, a volume adjust button, a mutebutton, a mode adjust button, a play/pause button, a skip button and arewinder button are displayed on the audio system control board 400 forcontrolling the audio system for example. The power button shown in FIG.4C may be understood as provided to remotely control power ON/OFF of theaudio system and the volume adjust button may be understood as providedto remotely control a volume of the audio system. Moreover, the mutebutton may be understood as provided to set the audio system to enter amute state and the mode adjust button may be understood as provided toadjust a play mode of the audio system. For instance, the play mode ofthe audio system may be set to at least one of a tape play mode, a CDplay mode, a DVD play mode, a radio mode, an external device connectmode, and a Bluetooth play mode. The play/pause button, the skip buttonand the rewinder button may be understood as provided to adjust aplay/pause, a skip and a rewinder of a multimedia content outputted viathe audio system, respectively.

Referring to FIG. 4D, a power button, a temperature adjust button, amode adjust button and an airflow adjust button are displayed on the airconditioner control board 400 for controlling the air conditioner forexample. The power button shown in FIG. 4D may be understood as providedto remotely control power ON/OFF of the air conditioner and thetemperature adjust button may be understood as provided to remotelyadjust a desired temperature in case of activating the air conditioner.Moreover, the airflow adjust button may be understood as provided toadjust an air conditioner airflow level and the mode adjust button maybe understood as provided to adjust an operating mode of the airconditioner. For instance, the operating mode of the air conditioner maybe set to one of a normal mode and a power-saving mode.

The types of the external devices shown in FIGS. 4A to 4D and the typesof the control buttons displayed on the control boards 400 are providedfor clarity and convenience of the description only, by which thepresent invention may be non-limited. It is a matter of course that thepresent invention is applicable to remotely controlling external devicesof which types are different from those of the former external devicesshown in FIGS. 4A to 4D. And, it is a matter of course that buttonsdifferent from those shown in FIGS. 4A to 4D can configure the controlboards 400. For instance, the mobile terminal 100 according to thepresent invention may be utilized as a remote controller configured toremotely adjust operations of at least one of an illumination device, awasher, a microwave oven and the like. And, a keypad for inputting textrings can be displayed on the control board 400. Moreover, it may beunnecessary for the control board 400 to include the tab button regionand the control button region, as shown in FIGS. 4A to 4D. For instance,if there is only one external device of a type selectable as a controltarget, the tab button region can be omitted from being displayed. Thenumber and/or types of control buttons displayable on the control board400 may be changeable depending on a state of an external device. Forinstance, if the external device in OFF state, the controller 180controls the power button to be displayed on the control board 400. Indoing so, if the external device enters ON state, the controller 180then controls additional control button(s) (e.g., a channel adjustbutton, a volume adjust button, etc.) to be displayed.

A remote controller program explained in the description of the presentinvention may support widgets. Hence, the control board 400 mentioned inthe foregoing description may be displayed as a full screen on thetouchscreen 151. Alternatively, the control board 400 may be displayedas a widget in a manner of overlaying a home screen (e.g., a basicscreen appearing on pressing a home button of a mobile terminal) or thelike.

After the external device to be remotely controller has been specified,if a user input is applied via the control board 400, the controller 180generates a control signal for controlling an operation of the externaldevice and is then able to remotely control the operation of theexternal device by transmitting the generated control signal to theexternal device. In particular, the controller 180 can transmit thecontrol signal to the external device via the wireless internet module113 or the short range communication module 114. In case that thecontrol signal is transmitted via the wireless internet module 113, anetwork address of the external device is set as a destination toprovide the control signal to the external device. In particular, thecontrol signal may be transmitted using TCP/IP (transmission controlprotocol/internet protocol) communication. In case that the externaldevice is remotely controlled using the TCP/IP communication, the mobileterminal 100 may receive feedback information on the control signal fromthe external device. In this case, the feedback information may meanoperating state information of the external device and an operatingstate changed by the control signal may be handled as the feedbackinformation. For instance, if the control signal is the signal forturning on/off the TV, the feedback information may be related to thepower ON/OFF state of the TV. If the control signal is the signal forchanging a channel of the TV, the feedback information may include theinformation on the changed channel of the TV. In order to transmit thecontrol signal via the short range communication module 114 usinginfrared (IrDA) communication, the short range communication module 14of the mobile terminal 100 should be situated to face the externaldevice (particularly, an infrared port of the external device) while themobile terminal 100 maintains a sufficiently close distance from theexternal device. If bidirectional IrDA communication is used, the mobileterminal 100 can receive the feedback information on the control signalfrom the external device.

The controller 180 of the present invention can determine a state of anexternal device based on at least one of a feedback information and amanipulation history of the external device.

For instance, if the controller 180 can receive the feedback informationfrom the external device, the controller 180 may be able to determinewhether the external device is in ON/OFF based on the received feedbackinformation. Even if the controller 180 does not receive the feedbackinformation from the external device, the controller 180 may be able todetermine an operating state of the external device based on a historyof user's manipulation on the control board. For instance, if a userinitially applies a power ON/OFF input of the control board once, thecontroller 180 recognizes the initial input as applied to turn on theexternal device. If the user applies the power ON/OFF input twice, thecontroller 180 determines it as inputted to turn off the externaldevice. And, the controller 180 can determine that the external devicein ON state until receiving the 2^(nd) power ON/OFF input since thereception of the 1^(st) power ON/OFF input.

In case of attempting to transmit a control signal using the IrDAcommunication, it may be necessary to specify an external devicemanufacturer. Since the compatibility of IrDA varies depending on adifference of IR code, a control signal compatible with an externaldevice of a 1^(st) manufacturer is not always compatible with anexternal device of a 2^(nd) manufacturer. Hence, before a control signalis transmitted by IrDA, a process for specifying a manufacturer of anexternal device needs to be performed in advance in order to check thecompatibility of a previous IR code. The process for specifying themanufacturer of the external device is described in detail withreference to FIG. 5 as follows.

FIG. 5 is a diagram for one example of a screen provided to specify amanufacturer of an external device.

Referring to FIG. 5, if a user input is applied to the setting button440 of the control board shown in FIG. 4, the controller 180 can controla setting screen of a remote controller program to be displayed [FIG. 5(a)]. On the setting screen shown in FIG. 5 (a), a device setting tab520 and a feedback setting tab 530 are displayed together with an autodisplay setting region 510 for example. An operation of the mobileterminal 100 related to the display setting region 510 shall bedescribed later.

The device setting tab 520 shown in FIG. 5 (a) enumerates types ofexternal terminals remotely controllable via the mobile terminal 100 andis provided to select at least one of the enumerated external terminalsas a target of a remote control. For instance, if a user applies a touchinput to each of ‘TV’, ‘settop box’, ‘audio’ and ‘air conditioner’regions shown in FIG. 5 (a), the controller 180 can control outputs ofcheck boxes 521 to 524 each of which whether a corresponding externaldevice is selected. Thereafter, based on the selected external device,the controller 180 can adjust an active tab configuration of the controlboard. For instance, referring to FIG. 5 (a), if the TV and the settopbox are selected [cf. ‘521’, ‘524’], the controller 180 can configurethe control board to remotely control the TV and the settop box only. Inthis case, unlike the former example shown in FIG. 4 showing that theactivation tabs of the TV, settop box, audio system and air conditionerare displayed, the controller 180 can control the activation tabs of theTV and the settop box to be displayed only.

Moreover, a user can select manufacturers of the external devicesenumerated on the device setting tab 520. For instance, if a user inputis applied to the TV setting button 525 [FIG. 5 (a)], the controller 180can control a selection screen, on which a list of TV manufacturers isenumerated, to be displayed [FIG. 5 (b)]. If the user selects one of themanufacturers from the list, the user can select the corresponding TVmanufacturer.

Once the user selects the TV manufacturer, the controller 180 can readout an IR code of the selected TV manufacturer from the memory 160.Thereafter, the controller 180 generates a test control signal using theread-out IR code and is then able to text a presence or non-presence ofcompatibility between the generated control signal and the externaldevice. In particular, the controller 180 displays a text page of theexample shown in FIG. 5 (c), generates a text control signal with an IRcode that matches the TV manufacturer, and is then able to transmit thegenerated text control signal to the external device. The user is thenable to complete the setting of the IR code by checking whether the textcontrol signal is compatible with the external terminal.

Yet, although an external device is released by the same manufacturer,it is not necessary to use the same IR code. If IR codes are differentdespite the same manufacturer, a plurality of test control signals maybe generated by changing the IR codes.

Besides, manufacturers can be selected for various external devicesincluding a settop box, an audio system, an air conditioner and the likeas well as a TV.

The ‘auto display’ region shown in FIG. 5 (a) is provided to adjustwhether to activate an auto display function. The auto display functionis to adjust an auto running of a remote controller program when themobile terminal 100 enters a preset network. While the auto displayfunction is active, if the mobile terminal 100 enters the presetnetwork, the controller 180 can automatically activate the remotecontroller program. For instance, when the preset network is a homenetwork, if the mobile terminal 100 enters the preset home network, thecontroller 180 automatically activates the remote controller program,thereby enabling a user to remotely control an operation of an externaldevice through the mobile terminal 100. The settings of the home networkcan be performed in a manner of registering AP information in advance,like the example which will be described with reference to FIG. 6 later.

The activation of the auto display function can be triggered after amanufacturer of an external device becoming a target of a remote controlhas been selected. Before the selection of the external devicemanufacturer, even if the auto display function is activated, it isunable to secure compatibility of a control signal using IrDA. A usercan manually adjust whether to activate the auto display function. Ifthe manufacturer of the external device is selected, the controller 180can control the auto display function to be automatically activated.

The feedback setting tab 530 shown in FIG. 5 (a) is provided to adjust afeedback output in response to a user input applied to a control board.While a touch sound item shown in FIG. 5 (a) is set active, if a touchinput is applied to a control board, the controller 180 can controlsound data to be outputted in response to the touch input to the controlboard. While a vibration item shown in FIG. 5 (a) is set active, if atouch input is applied to a control board, the controller 180 cancontrol vibration to be outputted in response to the touch input to thecontrol board.

Although the sound and vibration are taken as examples of feedbacktypes, they are just provided for clarity and convenience of thedescription. And, the present invention may be non-limited by the soundand vibration. Alternatively, instead of the sound and vibration types,a feedback can be outputted in type of LED flickering, color change of atouched point or the like. Moreover, it is a matter of course that afeedback can be outputted in a manner of combining at least two of theabove-enumerated feedback types.

In the following description, an operation of the mobile terminal 100according to the present invention is explained based on theabove-mentioned remote controller program.

FIG. 6 is a flowchart for controlling a mobile terminal according to thepresent invention. For clarity of the following description, assume thata state of an auto display function of a remote controller program isset to an active state.

Referring to FIG. 6, the controller 180 can register an AP (accesspoint) based on a user input [S601]. In particular, the controller 180controls AP information to be saved in the memory 160 based on the userinput, thereby completing the registration of the AP. In this case, theAP information may include at least one of a service set identifier(SSID) of the AP and a network address of the AP, by which the presentinvention may be non-limited. How the controller 180 registers the APbased on the user input is described with reference to FIG. 7 asfollows.

FIG. 7 is a diagram for one example to describe an AP registeringprocess.

Referring to FIG. 7, in an auto display setting region 710, if a touchinput is applied to a setting button 712 for adjusting detailed settingsof an auto display function [FIG. 7 (a)], the controller 180 can controlan AP list to be displayed [FIG. 7 (b)]. In the AP list, an AP currentlytransmitting a beacon signal to the mobile terminal and AP(s) havingtransmitted a beacon signal to the mobile terminal can be included.

FIG. 7 (b) shows one example that an AP having an SSID set to AP1 and anAP having an SSID set to AP2 are included in the AP list. The controller180 saves AP information of the AP selected by a user in the memory 160,thereby completing AP registration. Since the AP1 is selected in FIG. 7(b), the AP registration may be completed by saving the AP informationof the AP1 in the memory 160. In this case, the AP information mayinclude at least one of an SSI of the AP and a network address of theAP. In particular, the network address of the AP may include an IPaddress of the AP and/or a MAC address of the AP.

One example for registering an AP is described with reference to FIG. 7,by which the present invention may be non-limited. And, it is apparentthat the AP registering process can be performed by various methodsdevisable by those skilled in the art as well as by the process shown inFIG. 7.

Referring now to FIG. 6, if the wireless internet module 113 accesses arandom AP [S602], the controller 180 can determine whether the AP(hereinafter named an accessed AP) accessed by the wireless internetmodule 113 is a previously registered AP [S603]. In particular, thecontroller 180 determines whether an SSID and/or network address of theaccessed AP is identical to the previously registered AP information,thereby determining whether the accessed AP matches the previouslyregistered AP information.

If the accessed AP is the previously registered AP, the controller 180can control a control board for remotely controlling an external deviceto be displayed or may control the control board to enter an displayablestate [S604]. In this case, if the control board is displayed, it maymean that the control board is displayed as a full screen by activatinga remote controller program or that the control board is displayed as awidget of the remote controller program. Moreover, if the control boardenters the displayable state, it may mean that the control board is in adisplayable state by receiving a prescribed user input.

Thus, the controller 180 can output the control board as the full screenor the widget. The control board of the widget type can be outputted toa home screen, a status board, a locked screen and the like.

In case that a prescribed touch input is applied to a status bar fordisplaying an operating state of the mobile terminal 100, the statusboard may be provided to adjust ON/OFF of various modules of the mobileterminal 100 and to display various indication informations. Thecontroller 180 controls the control board of the widget type to bedisplayed on the status board, thereby increasing user's accessibilityto the control board. A process for outputting the control board to thestatus board is described with reference to FIG. 8 as follows.

FIG. 8 is a diagram for one example to describe a process for displayinga control board on a status bar.

Referring to FIG. 8 (a), the controller 180 can control a status bar810, which is provided to display an operating state of the mobileterminal 100, to be displayed on one side (e.g., a top end of thetouchscreen 151 shown in FIG. 8 (a)) of the touchscreen 151. On thestatus bar 810, such an operating state information of the mobileterminal 100 as an absent call indication, a new text message receptionindication, a vibration/sound mode setting indication, a current hour, aremaining battery level, a strength of signal received from a basestation and the like can be displayed.

While the mobile terminal 100 accesses a previously registered AP, if aprescribed touch input 820 (e.g., an action of dragging the status barin bottom direction) is applied to the status bar 810 [FIG. 8 (a)], thecontroller 180 displays a status board [FIG. 8 (b)] and then controls acontrol board 830, which is provided to adjust an operation of anexternal device, to be displayed on the status board.

If the status bar is exposed, the status board can be paged at any time.Hence, user's accessibility to the control board 830 can be enhanced.For instance, although such an operation as a web browser display, amusic play, a video play, a camera photographing and the like is beingperformed, if a user applies a prescribed touch input to the status bar810, it is able to remotely control an operation of an external deviceby paging the status board and the above-mentioned control board 830.

The controller 180 may control a control board to be displayed on alocked screen. Prior to describing a process for displaying a controlboard on a locked screen, the locked screen is described as follows.

First of all, if a prescribed condition is met, the controller 180 maycontrol the mobile terminal 100 to enter a power saving mode. In thiscase, the power saving mode is to deactivate a touchscreen having highpower consumption in order to raise battery power efficiency. Forinstance, if a touch input is not applied to the touchscreen 151 for aprescribed duration or a user applies a user input to an externalbutton, the controller 180 may control the mobile terminal 100 to enterthe power saving mode. While a mode of the mobile terminal 100 is set tothe power saving mode, if a prescribed user input is applied, thecontroller 180 may control a locked screen to be displayed on thetouchscreen 151. The locked screen ignores touch inputs other than apreset meaningful touch input, thereby preventing wrong inputs appliedby a user.

If the power saving mode of the mobile terminal 100 having accessed thepreviously registered AP is cancelled, the controller 180 of the presentinvention can control a control board to be displayed on a lockedscreen. A process for displaying a control board on a locked screen isdescribed in detail with reference to FIG. 9 as follows.

FIGS. 9A to 9C are diagrams for one example to describe a process fordisplaying a locked screen including a control board.

Referring to FIGS. 9A to 9C, as the touchscreen 151 is turned off in themobile terminal 100 in a power saving state, any information is notdisplayed [FIG. 9A]. Thereafter, if a prescribed user input 910 isapplied to the mobile terminal 100 (e.g., a user input is applied to anexternal key in FIG. 9A), the controller 180 turns on the touchscreen151 and is then able to control a locked screen to be outputted [FIG.9B]. In doing so, if the mobile terminal 100 is currently connected to apreviously registered AP, the controller 180 can control a control board920 to be displayed on the locked screen [FIG. 9B].

The controller 180 handles a user touch input to the control board 920as a meaningful input, thereby enabling a user to remotely control anoperation of an external device without unlocking the touchscreen 151.And, the user may select a type of an external device to control througha tab button provided to the control board 920.

Unlike the example shown in FIG. 9B, if a plurality of external devicesare set as remote control targets (cf. the device setting tab 520 shownin FIG. 5 (a)), the controller 180 may control a plurality of controlboards to be displayed to control a plurality of remote devices selectedas the remote control targets, respectively.

For instance, if there are two remote devices (e.g., TV and settop box)selected as the remote control targets, referring to FIG. 9C, thecontroller 180 can control two control boards 922 and 924 to bedisplayed. Thus, if there are N remote devices selected as the remotecontrol targets, the controller 180 may control N control boards to besimultaneously displayed.

If a touch is inputted to a close button 930 of the control board 920,the controller 180 may control the control board to stop beingdisplayed. In particular, a user can control the control board to stopbeing displayed at any time.

While the locked screen is displayed, if a prescribed touch input isapplied to the control board 920, the controller 180 may control thelocked screen of the touchscreen to be cancelled (i.e., unlocked). Forinstance, referring to FIG. 9B and FIG. 9C, if a touch input fordragging a handler 940 displayed on one end of the control board 920 ina prescribed direction is received, the controller 180 may control thelocked screen of the touchscreen 151 to be cancelled.

Of course, without using the control board 920, it is able to cancel thelocked screen of the touchscreen 151 by a conventional method (e.g., aprescribed touch input applied onto a lock icon 950).

Once the locked screen of the touchscreen 151 is cancelled, thecontroller 180 may control a control board to be re-displayed as awidget on the home screen or the status board or may control the controlboard to be outputted as a full screen.

According to another embodiment of the present invention, the controller180 can determine whether to keep running a remote controller programdepending on a method of cancelling a locked screen of the touchscreen151. In particular, the controller discriminates a case of cancelling alocked screen based on a touch input applied to the control board 920from a case of cancelling a locked screen based on a touch input appliedto an outside of the control board 920 and is then able to determinewhether to keep running the remote controller program.

For instance, as a touch input is applied to the handler 940 of thecontrol board 920, if the locked screen is cancelled, the controller 180determines that the control board 920 is intended to keep being usedafter the cancellation of the locked screen of the touchscreen 151 andmay control the control board 920 to keep being displayed. On the otherhand, if the locked screen is cancelled based on a touch input to thelock icon 950, the controller 180 determines that the control board 920is intended not to keep being used and may control the control board 920to stop being displayed after the cancellation of the locked screen ofthe touchscreen 151.

According to the embodiment shown in FIG. 9, if a prescribed user inputis applied to the touchscreen 151 in a power saving state, thecontroller 180 turns on the touchscreen 151 and a locked screen havingthe control board 920 displayed thereon is outputted. According toanother example of the present invention, while a locked screen isoutputted through the touchscreen 151, if a prescribed user input (e.g.,a push to a home button) is applied, the controller 180 may control thecontrol board 920 to be displayed on the locked screen.

While the mobile terminal 100 is connected to a previously registeredAP, a control board is displayed, or a control board displayable stateis maintained, if there is an incoming call to the mobile terminal 100or a user answers an incoming call, the controller 180 can transmit acontrol signal, which is generated to automatically lower (or mute) avolume of such an audio output device as a TV, an audio system and thelike, to an external device. If determining that the phone call isended, the controller 180 may control the volume of the audio outputdevice such as the TV, the audio system and the like to automaticallyreturn to the previous volume. While a phone call is made, thecontroller 180 may control a voice in the phone call to be outputtedthrough the TV, the audio system or the like.

While the mobile terminal 100 is connected to a previously registered APor a control board displayable state is maintained, if there is anincoming video call to the mobile terminal 100, the controller 180 maycontrol the video call to be displayed through such a video outputdevice as a TV and the like.

If the wireless internet module 113 cancels the access to the previouslyregistered AP [S605], the controller 180 stops displaying the controlboard and may control the remote controller program to be automaticallyended [S606].

In the example shown in FIG. 6, the activation or termination of theremote controller program is automatically adjusted depending on theaccess to the previously registered AP or the cancellation of theaccess. Yet, it may not be mandatory for the activation or terminationof the remote controller program to be automatically performed. Thecontroller 180 may control the activation or termination of the remotecontroller program based on a user's input. In doing so, an activate/endbutton of the remote controller program may be provided as a quick iconthat is paged from the status bar.

For instance, referring to FIG. 8 (b), based on a touch input to a quickicon button 840 named ‘remote controller’, the controller 180 cancontrol activation and termination of the remote controller program.Even if the mobile terminal 100 is not connected to the previouslyregistered AP, the controller 180 may control the remote controllerprogram to be activated through a touch input to the quick icon button840. On the contrary, even if the mobile terminal 100 is currentlyconnected to the previously registered AP, the controller 180 maycontrol the remote controller program to be terminated through a touchinput to the quick icon button 840.

In the above-described example, the mobile terminal 100 according to thepresent invention is able to transmit a control signal to an externaldevice using at least one of the wireless internet module 13 and theshort range communication module 114. In case of transmitting a controlsignal using the short range communication module 114 by IrDAcommunication, there is such a limitation that the short rangecommunication module 114 should face the external device. Yet, in caseof transmitting a control signal using the wireless internet module 113,there is no such limitation.

In case that the mobile terminal 100 is able to transmit a controlsignal using both of the wireless internet module 113 and the shortrange communication module 114, the controller 180 may control thecontrol signal to be transmitted by selecting one of the communicationmodules depending on directionality of the mobile terminal 100. Inparticular, in case of detecting that the mobile terminal 100 hasinclined over a prescribed angle through the sensing unit 140, thecontroller 180 can transmit the control signal via the wireless internetmodule 113. Otherwise, the controller 180 can transmit the controlsignal via the short range communication module 114.

For another instance, in case that a control signal is generated whilean output mode of the touchscreen 151 is set to a landscape mode, thecontroller 180 can control the control signal to be transmitted usingthe wireless internet module 113. For another instance, in case that acontrol signal is generated while an output mode of the touchscreen 151is set to a portrait mode, the controller 180 can control the controlsignal to be transmitted using the short range communication module 114.

In particular, as the mobile terminal 100 inclines over the prescribedangle, if the output mode of the touchscreen 151 is set to the landscapemode, the controller 180 determines that the short range communicationmodule 114 of the mobile terminal 100 does not face the external device.Hence, the controller 180 transmits the control signal of nodirectionality using the wireless internet module 113.

On the contrary, while the output mode of the touchscreen 151 is set tothe landscape mode, the short range communication module 114 may be setavailable. Moreover, while the output mode of the touchscreen 151 is setto the portrait mode, the wireless internet module 113 may be setavailable.

In case that the mobile terminal 100 is able to transmit a controlsignal via the short range communication module 1143 only (e.g., anetwork address of an external device is unknown or the mobile terminal100 or the external terminal is not in a wireless internet accessedstate), if the output mode of the touchscreen 151 is switched to thelandscape mode from the portrait mode, the controller 180 can controlthe remote controller program to be automatically ended. In particular,if the mobile terminal 100 is determined as not facing the externaldevice, the controller 180 determines that the external device isintended not to be remotely controlled any more, the remote controllerprogram can be automatically ended.
